Product Overview
641-12 is a series 641 air velocity transmitter. It is ideal instrument for monitoring air flow. This transmitter uses a heated mass flow sensor which allows for precise velocity measurements at various flow rates and temperatures. Typical applications include exhaust stack flow monitoring, HVAC air velocity measurements, clean room fresh air supply, air control in drying processes, fan supply and exhaust tracking and ensuring proper lab hood exhaust flow rates.
- 12" probe length
- Field selectable ranges from 250FPM (1.25m/s) to 15,000FPM (75m/s) suit any application
- Easy push button set-up reduces installation time
- Compact housing minimizes installation footprint
- 4-20mA output for use with most building management systems
- Digital filter for signal damping
- Selectable 0.5 to 15 (seconds) output filter
- 1/2˝ male NPT process connection and screw terminal electrical connection
- Maximum 300mA current consumption and 600 ohm loop resistance
- Unit not position sensitive, probe must be aligned with airflow
